The journey from DOS to AI
By Paul Harwood (betterchess.net)
The Fritz series has undergone a remarkable transformation since its humble beginnings as a simple DOS program that could be easily defeated by amateur players. Today’s Fritz 20 stands as a formidable opponent capable of challenging world champions, while serving as an intelligent training partner that adapts to individual playing styles and skill levels.

Enhanced human-like playing experience
Building upon the “human” playing concept introduced in Fritz 19, Fritz 20 takes artificial personality to new heights. The engine has been deliberately calibrated to be less tactically precise overall, focusing instead on a more positional style of play that mirrors human decision-making processes. This approach makes Fritz 20 less punishing of mistakes while providing a more realistic and educational playing experience.
New opponent personalities
Fritz 20 introduces several exciting new opponent types that cater to different playing styles and learning objectives:
Your personal chess trainer. Your toughest opponent. Your strongest ally.FRITZ 20 is more than just a chess engine – it is a training revolution for ambitious players and professionals. Whether you are taking your first steps into the world of serious chess training, or already playing at tournament level, FRITZ 20 will help you train more efficiently, intelligently and individually than ever before.
Hypermodern style: This personality employs flank openings like the Reti Opening and controls the center through piece placement rather than pawn advances, offering players exposure to hypermodern chess principles in practical play.
Configurable opponent: Perhaps the most innovative feature, this option allows players to customize their opponent’s characteristics using the style analysis framework from ChessBase 18. The system includes preset configurations modeled after chess legends including Fischer, Tal, Karpov, Capablanca (my personal favorite) and Lasker, complete with their characteristic opening repertoires and playing styles.
VIP personalities: The program offers additional legendary playing styles including Morphy, Lasker, and Capablanca, allowing players to experience games against some of history’s greatest chess minds.
Additional styles: Fritz 20 also introduces “Romantic” style for those who prefer tactical fireworks and combinational play.
Revolutionary AI commentary and voice features
One of Fritz 20’s most groundbreaking features is its integration of artificial intelligence for real-time commentary and voice interaction. The program can speak during games, offering situation-specific chess commentary that goes far beyond generic observations. With recognition of 170 different chess themes and patterns, Fritz provides varied and contextually relevant insights throughout the game.
The AI commentary system generates fresh content continuously, ensuring that players don’t encounter repetitive observations. The feature supports multiple languages and assigns unique voices to different opponent personalities, creating an immersive and personalized experience. The AI even demonstrates creativity, occasionally offering commentary in rhyming couplets or even limericks, adding an element of humor to the learning process.
Significant engine improvements
Under the hood, Fritz 20 features Frank Schneider’s substantially improved engine, boasting over 100 Elo points of strength gain compared to Fritz 19. This improvement translates to an estimated rating of approximately 3,580 Elo, placing it among the elite chess engines available today.
The engine’s performance was validated at the 2024 Computer Chess World Championship in Santiago de Compostela, where it shared first place among nine participants in the software category. The engine incorporates neural network evaluation, aligning with modern chess programming standards while maintaining its distinctive character that often provides alternative suggestions to the ubiquitous Stockfish engine.
Enhanced training features
Bullet training mode
Fritz 20 introduces a specialized Bullet Training mode designed to improve players’ performance under extreme time pressure. This feature allows precise time limit configuration, helping players develop the reflexes and nerve control essential for success in blitz and bullet games on online platforms.
Realistic time management
The program now operates with realistic time allocation, mimicking human time management patterns. Players can configure Fritz to play at different speeds, enabling various training scenarios such as practicing time pressure technique or learning to convert advantages in time scrambles.
Visual and interface improvements
Following the design language established by ChessBase 18, Fritz 20 features a completely redesigned user interface with modern, consistent button layouts and improved visual aesthetics. The program includes new fully animated 3D boards that enhance the visual appeal while maintaining the functional excellence that Fritz users expect.
Market position and accessibility
Fritz 20 is available through ChessBase’s official store, with upgrade pricing available for existing Fritz 19 users. The program continues ChessBase’s tradition of making sophisticated chess software accessible to players of all levels, from ambitious beginners to experienced tournament competitors.
